PUMP.

SPECIFICATION formingpart of Letters Patent No. 266,117, dated October17, 1882.

Application filed J une 25, 1881. (No model.)

T 0 all whom it may concern Be it known that I, JOSEPH P. ELLACOTT, acitizen of the United States, residing at Ohicago, in the county of Cookand State of Illinois, have invented certain new and usefulImprovements'in Pumps, set forth in the following specification,reference'being had to the accompanying drawings, in which- Figure 1represents a front view of the pump. Fig.2 represents a vertical sectiontaken on the line 00 00, Fig. 1. Fig. 3 represents the pumphandle and anend view of one of its arms. Fig. l'represents a plan section taken onthe line y y, Fig. 2. Fig. 5 represents a plan section taken on the line22, Fig. 2. Fig. 6 represents a plan section taken on the line o n, Fig.2, and Fig. 7 represents a plan section taken on the line to 10, Fig. 2.7

My invention relates more particularly to .pumpsused with stationarywash-bowls in railway-cars, but may be used in otherpumps' also.

The invention consists in a pump provided with a discharge-passage whichis contracted at a point below its highest part; and it further consistsin means for adjusting the spout and handle. independently or together.

The same letters refer to the same parts in all the figures.

1n the drawings, A is the pump-stock of a pump embodying myimprovements. B is a secondary cylinder, which depends from and is castsolid with the laterally-adjustable screwthreaded pump-top a, whichforms a support for the pump by resting on the marble slab O or othersupport. In this cylinder B works the piston D, forcing wateralternately with, but rising and falling simultaneously with, theordinary lifting-piston, E, to which it is connected by aconnecting-rod, d, both pistons being rigidly secured thereto. Thispiston E is provided with an ordinary valve, 0, and below it, at thebottom of the pump, is a flapyalve, F, of ordinary construction, whichopens and closes the suction-pipe G. The tapped sleeve or collar H,screwed around the body of the pump below the support 0, acts on theprinciple of and forms a set-nut to secure the pump firmly to thesupport 0, without regard to the angle at which the pump-top a is left.The pumptop a has cast with it a six-sided chamber, a,

formed by the side and top of the pump-top a, theside of the cylinder B,the shelf a projecting from said cylinder B to the outer wall ofpump-top a, and'two upright plates, 0. a the side of the chamber aformed by the side of the pump top having an opening which is tapped forthe insertion of spout a. The shelf a is bored vertically for theinsertion of pipe I, which has a contracted part, i, at some distancefrom its top.

J is the pump-handle, with armsjj, one of which is jointed to theconnecting-rod j which drives the pistons, and the other of which ispivoted at the top of the standard K, cast on the laterally-adj ustablesecondary pum p-top L, which top L has an opening, in which plays theconnecting-rod j a screw-threaded annular flange, l, by which said top Lis secured to the rest of the pump, and a set-screw, Z on a part of topL projecting beyond said flange l. The workingcapacity of the secondarycylinder and its piston is preferably about half that of the maincylinder and piston.

It will readily be seen that when the pumptop a, with pipe I secured toit, is screwed on, an air-chamber M, is formed between cylinder 13 andthe sides of the pump.

The operation of the pump is as follows: On the upward stroke of thepistons water is sucked up through valve F, and part of that above thevalve 0 is discharged through pipe I, a part follows piston D upcylinder B, and the remainder enters the air-chamber M, compressing theair therein. On the downward stroke the valve F is closed and thecylinder B discharges its contents partly through pipe I and partly intothe air-chamber M. Atthe ends and beginnings of strokes the air in theair-chamber M, by its pressure, tends to equalize the flow through pipeI, and by its elasticity tends to prevent pounding. The pipe I iscontracted in order to impede the discharge of water, and thus secure amore effective pressure from the air-chamber at the beginnings and endsof strokes. By making the contracted part i in pipe Iat some distancebelow the outlet ofpipe I there is always a quantity of water above thecontracted part t'. The small stream which passes through the contractedpart i into the laterally greater body of water above comes out 2 f 2mm[7 into the chamber a a broader and slower stream. The object ofretarding the speed of the discharge is to prevent splashing, and theadvantage of this method of so doing is that the friction which slackensthe speed of the water increases its volume.

The spout a, being secured to the-top a, may be adjusted to differentangles by slightly screwing up or unscrewing the top a. The handle J isadjustable similarly by turning the top L.

Obviously some parts of the above-described apparatuses may be changedin details of construction without departing from the main features ofmy invention, by means of which the operations above described aresecured. I do not wish to be understood, therefore, as limiting myinvention to the apparatuses in all their details as herein shown anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a pump, the pipe I, with contracted part i, a valve, I piston E,carrying a valve, 6, air-chamber M, and cylinder B, with piston D, allcombined and operating substantially as set forth.

2. In a pump, an adjustable top to which a spout is attached, incombination with a secondary top, which supports the handle and isadjustable independently of the former, whereby the lateral adjustmentof the spout and handle may be etfected independent of each other,substantially as described.

3. The pump-stock A, in combination with the top a, secured to the upperend of the former by a screw-thread, so as to be adjustable thereon, thespout attached to said top, the top L, secured to the top a by ascrew-thread, so as to be adjustable on said top, and the handle J,connected to and supported by the top L, substantially as and for thepurposes set forth.

4. The pump-stock A, in combination with the top a, secured to the upperend of the former by a screw-thread, so as to be adjustable thereon, thespout attached to said top, the top L, secured to the top a by ascrew-thread, so as to be adjustable on said top, the handle J,connected to and supported by the top L, and the set-screw 1substantially as and for the purposes set forth.
